T0 at whom, it may concern.-

Be it known that I, GEORGE F. LARKIN, a citizen of the United States,residing at No. 187 Broad street, Newark, county of Essex, State of NewJersey, have invented certain new and useful Improvements inI-Iat-Pouncin g Machines, fully described and represented in thefollowing specification and the accompanying drawings, forming a part ofthe same.

The present invention relates to that class of hat-pouncing machines inwhich an endless pouncing-belt is used; and the object of the inventionis to furnish means whereby the belt may exert an elastic pressure uponthe surface of the hat, the pressure upon the inner or outer edge of thebrim may be varied at pleasure, the belt kept in its proper positionupon the driving-roll automatically, and the feeding-rolls adjusted togrip the inner and outer edge of the brim in the desired manner andpropel it in the required direction.

The improvements also include means for varying the relation of thetension-roll to the driving-roll of the pouncing-belt and means fordriving the lower feed-roll from the main shaft of the machine.

In the annexed drawings, Figure 1 is a front elevation of the machine.Fig. 2 is an elevation upon the right hand side of the same; Fig. 3, anelevation of the roll-adj usting devices viewed from the left-hand sideof the machine. Fig. 4 is a plan of the guide for the pouncing-belt witha section of the belt. Fig. 5 is a section of one of the pressure-rolls,showingthe rubber facing; and Fig. 6, a plan of the bracket to carry thefeed-rolls.

adesignates the side frames of the machine, connected by tie-bars b. Thedriving-shaft c is propelled by fast and loose pulleys cl and carriespulleys fand g, provided, respectively, with belts f and g to drive thepouncing-roll shaft h and feed-roll shaft 70.

The feed-rolls 2' and j are journaled in the bearings Z and m, each ofwhich is provided intermediate to its ends with a lug n, and the lugsare connected by a pivot-bolt 0,which serves to clamp the two lugstogether and hold the bearings in a fixed position when adjusted. v

The upper feed-roll is carried by shaft and the shafts 7t and 7c areconnected by gears 11. A pulley m upon the shaft 70 receives the belt gto drive the rolls as required. The lower bearing Z is attached to around post w, and a vertical socket 20 upon the frame serves to supportthe post adjustably. With this construction the post may be rotated toturn the feed-rolls t' andj at different angles to the pouncing-belt,and thus draw the brim through the same in the best manner, and the postalso affords the means of adjusting the feedrolls vertically, beingclamped in the socket 10 when adjusted by the set-screw Z. Thedriving-roll p propels the pouncing-belt q, and a tension-rollr isarranged directly above the roll 19 and has its shaft r journaled inbearings upon one arm of a lever 8. At the opposite end from the shaft1' the lever s is provided With a weight 5 which may be adjusted uponthe lever to vary the yielding draft exerted by the tensionroll upon thepouncing belt. Such weight and lever oper ate to produce an elastictension in the belt, which prevents it from slipping upon thedriving-roll when the belt gets loose, as sometimes occurs through wearand atmospheric influences. The fulcrum s of the lever s is horizontallypivoted in a fulcrum-frame t, and such frame is also pivoted by bolt itupon a bracket 12, so as to tip the fulcrum s in a vertical plane andvary the relation of the tension-roll r to the driving-roll p. 1

Such variation inclines the belt to run toward the inner or outer endsof the rolls, and thus controls the position of the belt at pleasure.The bracket 0 is shown bolted upon the frame adjacent to the inner endof the driving-roll; but the fulcrum-frame may be pivoted upon themachine-frame in any convenient'manner. A screw 11, is inserted througha slot upon the bracket o into the fulcrum-frame to clamp the same whenadjusted. The hat-brim is pressed toward the under side of thedriving-roll p, where the pouncing-belt is supported by a pressure-rollp, journaled upon the end of a hinged arm m, which is pivoted upon astud a7, adjust able in a vertical plane to set the inner or outer endof the roll 1) nearest to the roll 10. The arm w is provided with astud, upon which the pressure-roll p is journaled, and such arm beingmounted upon the stud as is infiuenced by any variation in theinclination of the stud m, which is affected by the adjustment of theplate 2. Such adjustment of the stud 00 correspondingly affects theposition of the pressure-roll and varies its line of contact with thepouncing-belt. A treadle y is connected by a rod 3/ to the outer end ofthe arm at to force the pressure-roll toward the driving-roll p, andthus hold the hat-brim against the pouncing-belt as the brim is drawnbetween the two rolls by the feed. The stud m is projected from a hingedplate 2, whichis pivoted to the machine frame atthe upper end andsecured adj ustably at the lower end by nut 2 on a bolt z. (See Fig.3.)"

A set-screw q passes through the frame against the rear side of theplate .2, and thus serves to tip the stud and to adjust thepressure-roll p at the required angle to the driving-roll p. Each ofthese rolls is formed with a collar at each end, forming a rectangulargroove or recess around the periphery, into which an endless rubber bandp is shrunk to form an elastic jacket upon theroll. Such jacket in thecase of the roll 10 sustains the pouncing-belt elastically, while thejacket upon the roll p supports the hat-brim elastically against thepouncing-belt. The brim is thus supported elastically and thecuttingsurface of the belt therefore operates more freely and is lessliable to clog or become jammed against the felt than where supportedupon a rigid surface. The fitting of the elastic rubber band 132 into arectangular groove upon the surface of the roll 10 p secures a renewablesurface which may be readily removed and replaced when worn.

It will be understood that a belt running at high speed freely over tworolls is very liable to shift laterally and run off the rolls if thebelt be not guided accurately, as shown in Fig. 5. It is therefore mostimportant that the hat-brim should be fed betweenthe rolls p and p atexactly the right angle, the

tension-roll 7' should set at the right angle with the driving-roll p,and the pressure-roll p should not press any harder upon one edge of thebelt than upon the other. To secure and maintain such adjustments hasbeen very difficult in the machines heretofore used; but all of suchadjustments are readily efl'ected with the construction describedherein. To positively control the position of the belt in case any ofthe adjustments is defective, I provide a further security in a Wedge a,which is mounted adj ustablyintermediate to the rolls 1') and r, withits slanting edges in co'ntactwith the rear edges of the belt. The wedgeis mounted upon a stand I) over the front bearing vof the'driving-rolland is adjusted by means of a screw 0 to press within the edges of thebeltin the required degree. It has been found in practice that theslightest touch of such wedge suffices to drive the belt forwardly uponthe rolls, and thus holds it in any requiredworking position withoutinjury to the belt.

cases to set the junction of the feed-rolls a little above or below thejunction of the pres sure-roll and driving-roll, as the draft of thebrim against the pouncing-belt is thus varied and the belt is caused tooperate with more or less effect upon the brim..

With a thick brim the rolls maybe set above the bottom line of thedriving-roll and the brim thus drawn upwardly and its surface kept incontact for a longer time with the -pouncing-'belt than if the brim weredrawn downwardly along the surface of the pressureroll. To effect suchadjustment with accuracy, a set-screw i) may be mounted upon the bracket72 below the post 10, and the post supported and. adjusted by suchset-screw. It also facilitates the adjustment of the feedinguollS in anexact relation to the pouncingbelt to make the bracket 12 adjustableupon the frame, which is effected. by providing a horizontal seat a uponthe frame below the feed-roll bearings and forming the foot of thebracket, as shown in Fig. 6, with a longitudinal slot Z in line with theaxis of the feed-rolls. A bolt y inserted through such slot into theseat serves to hold the bracket adjustably. The adjustments described atford a means of feeding the hat-brim through the pouncing devices in themost perfect manner and greatly diminish the labor of. attending themachine and preserving its efliciency.
